How to generate List of all ProjectAreas with Plain Java API

IProjectAreaHandle matchingProjectArea = null;

IItemType itemType= IProjectArea.ITEM_TYPE;

IDynamicQueryModel model= itemType.getQueryModel();

IItemQuery query= IItemQuery.FACTORY.newInstance((IItemQueryModel) model);

ItemQueryIterator<IProjectAreaHandle> iterator= new ItemQueryIterator<IProjectAreaHandle>(getAuditableCommon(), query);

List <IProjectAreaHandle> projectAreas = iterator.toList(monitor);

for (IProjectAreaHandle pa : projectAreas){

    		IProjectArea projectArea = (IProjectArea) repo.itemManager().fetchCompleteItem(pa, IItemManager.DEFAULT, monitor);
    		String projectAreaName = projectArea.getName();    
    		// Keep adding project area name to a list.

}
